My office just bought several Toshiba Portege M800 (PPM817-05602D) and we've downgraded them to Windows XP. I've found and installed all the drivers (Device Manager says that they're all working). Everything works as it should except the sound. When I attempt to go into the Sound options in the Control Panel everything is greyed out and it says a device can't be found.
I've done the following
- re-installed the sound drivers
- un-installed and re-installed the device in the device manager
- tried a slew of other sound drivers in a desperate attempt
- BIOS settings (there are no sound settings in the BIOS)
Any input would be greatly appreciated.
